1. Field of the Invention
The present invention relates to a charging cable support aim which supports a charging cable for charging an electric vehicle.
2. Description of Related Art
For charging an electric vehicle, it has been common that the vehicle is parked in parking space such as a parking area, a charging cable connected to a dedicated charging device installed beside the parking space is drawn around, and a charging connector provided at the distal end of the charging cable is connected to a charging port of the electric vehicle (for example, see Japanese Patent Application Publication No. 2012-19633).
In this case, by extending the length of the charging cable, the charging cable can be easily connected to the electric vehicle, and the electric vehicle is charged without taking into consideration of how the electric vehicle is parked or the position of the charging port.
However, in the above case, if the charging port of the electric vehicle is away from the charging device, the charging cable is drawn around on the ground. This causes abrasion of the charging cable leading to deterioration thereof, and causes the charging cable to be dirty with mud or the like, which makes it difficult to handle the charging cable.
Therefore, as shown in Japanese Patent Application Publication No. 2006-136182, for example, it has been considered that suspension fittings are provided on a ceiling to suspend the charging cable at mid-portions thereof, so that charging operation is performed by pulling out the charging cable without bringing it into contact with the ground.
However, using the suspension fittings as in Japanese Patent Application Publication No. 2006-136182 above poses the following disadvantages. First, parking areas provided with a ceiling are limited in number. Moreover, even when such suspension fittings can be provided, the area where the charging cable is movable is limited to the area below the provided suspension fittings, and thus, the charging cable using such suspension fittings cannot be used for some types of vehicles in which the position of the charging port of the electric vehicle is different. Moreover, even with the same vehicle, if it is parked in an opposite direction, the charging port is positioned at a completely different position, which also prevents smooth charging operation.
Therefore, in view of the above disadvantages, an object of the present invention is to provide a charging cable support arm which supports the charging cable such that even in a parking area without a ceiling, the charging cable can be connected to the charging port of the electric vehicle at any position without bringing the charging cable into contact with the ground.
In order to solve the above disadvantages, a first aspect of the invention is a charging cable support arm including a support member that is configured to be fixed to a wall face or a support post, a first arm whose proximal end portion is hinged to the support member and that is rotatable within a horizontal plane, and a second arm that is hinged to a distal end of the first arm and that is rotatable within a horizontal plane. The first arm is provided with an insertion hole through which a charging cable is inserted into the first arm. The second arm is provided with a pull-out hole at a distal end thereof or near the distal end, and the inserted charging cable is pulled out from the pull-out hole. By use of the charging cable pulled out of the pull-out hole, an electric vehicle is charged.
According to this configuration, the support member is fixed to a position higher than the electric vehicle, and charging is performed by use of the charging cable which is supported by the arms foldable in two stages and pulled out of the pull-out hole of the second arm. Thus, even in a parking area without a ceiling, the charging cable can be moved in a preferable manner. Accordingly, the electric vehicle can be charged without bringing a mid-portion of the charging cable into contact with the ground, and thus, dragging the charging cable to cause deterioration thereof, making the charging cable dirty with mud, or the like is eliminated.
A second aspect of the invention is a charging cable support arm in the configuration according to the first aspect, in which the second arm is hinged to the first arm so as to rotate to an angle at which the second arm becomes parallel to and faces the first arm. Either one of the first arm and the second arm is provided with a magnet for attracting and holding the other counterpart facing thereto.
According to this configuration, the second arm folded to face the first arm is maintained by the magnet.
A third aspect of the invention is a charging cable support arm in the configuration according to the first or second aspect, in which the support member is fixed to the wall face, the first arm is hinged rotatably in one specific direction to an angle at which the first arm becomes parallel to the wall face to which the support member is fixed, and the support member has an engagement portion which engages a side portion of the first arm when the first arm is rotated and arranged in parallel to the wall face. The engagement portion or the side portion of the first arm facing the engagement portion is provided with a magnet for attracting and holding the engaged counterpart.
According to this configuration, the state where the first arm is parallel to the wall face is maintained by the magnet. Thus, while the charging cable support arm is not used, the charging cable support arm can be held in close contact with the wall face.
A fourth aspect of the invention is a charging cable support arm in the configuration according to the third aspect, in which the first arm and the second arm each have a substantially identical length, and the first arm and the second arm are each hinged so as to be rotatable by substantially 180 degrees.
According to this configuration, the first arm can be rotated about the installation portion of the wall face serving as the center, to be arranged in parallel to the wall face either on the left or right side. The distal end of the second arm can be moved along the arc of a substantially semicircular shape having a radius of a length obtained by adding the length of the first arm and the length of the second arm together. Further, the second arm can be moved along the arc of a substantially semicircular shape having a radius of the length of the second arm about the distal end of the first arm serving as the center. Therefore, the charging cable pull-out hole can be moved in a wide range, the area where the charging cable is suspended is wide, and, for any position of the charging port of an electric vehicle, charging can be performed without bringing the charging cable into contact with the ground.
According to the present invention, the support member is fixed to a position higher than the electric vehicle, and charging can be performed by use of the charging cable supported by the arms foldable in two stages. Therefore, the electric vehicle can be charged without bringing a mid-portion of the charging cable into contact with the ground, and dragging the charging cable to cause deterioration thereof, making the charging cable dirty with mud, or the like is eliminated.
Hereinafter, an embodiment implementing the present invention will be described in detail with reference to the drawings.
A charging cable support arm 10 includes a support member 1 to be fixed to a wall face, a first arm 2 whose proximal end portion is hinged to the support member I, and a second arm 3 hinged to the distal end of the first arm 2. Each of the support member, the first arm 2, and the second arm 3 is formed by bending a steel plate.
The support member 1 has an arm support face 11 substantially at its center. A hinge 4 is mounted on the arm support face 11 to hinge the first arm 2 thereto. In the support member 1, the aim support face 11 is arranged so as to protrude, with left and right portions of the arm support face 11 being bent rearward, and side plates 12 formed by being bent are respectively provided with fixing faces 13 at rear portions thereof. The fixing faces 13 extend in the left and right directions so as to be fixed to the wall face.
The first arm 2 is a tubular body having a quadrangle shape in its cross section. A reinforcement plate 21 is mounted to the first arm 2 so as to mount the hinge to a proximal end portion of the first arm 2 that is one end serving as the center of rotation. The reinforcement plate 21 is welded to the right face of the first arm 2, and is bent in an L-shape to form a rear plate 21a of the first arm 2.
The support member 1 and the reinforcement plate 21 each have a width sufficiently larger than the width (the width in the up-down direction) of the first arm 2. The first arm 2 is rigidly hinged by use of two hinges 4 so as to be rotatable in a semicircular shape within a horizontal plane, from a state where the hinges 4 are closed to a state where the hinges 4 are open by 180 degrees.
When the hinges 4 are open by 180 degrees to arrange the first arm 2 in parallel to the wall face, the rear plate 21a abuts against the side plate 12 of the support member 1, whereby further rotation of the first arm 2 is prevented and contact thereof with the wall face is prevented.
As shown in the enlarged view of
To the right face of the first arm 2 corresponding to the first magnet 14A, a contact piece 14a for reinforcing a portion that comes into close contact with the first magnet 14 and for ensuring the close contact is mounted.
On the other hand, a magnet (second magnet) 22 is mounted to a proximal end portion of the left face of the first arm 2. Accordingly, the second arm 3 folded as shown in
Similarly to the first aim 2, the second arm 3 is a tubular body having a quadrangle shape in its cross section, and is hinged to be coupled to the distal end of the first arm 2 via a hinge shaft 31, so as to rotate on the same plane as the plane on which the first arm 2 rotates. Specifically, the second arm 3 is hinged to the first arm 2 so as to be rotatable substantially by 180 degrees, from a state where the second arm 3 is straightly aligned with the first arm 2 to a state where the second arm 3 rotates leftward to be parallel to and face the first arm 2 as shown in
The charging cable is inserted in the first arm 2 between the first passage hole 24a formed near the proximal end portion of the first arm 2 and the second passage hole 24b formed at the distal end portion thereof, and inserted in the second arm 3 between the third passage hole 34a formed near the proximal end portion of the second arm 3 and the fourth passage hole 34b formed at the distal end portion thereof, whereby mid-portions of the charging cable are supported.
The charging cable 40 has its proximal end portion connected to the charging device 41, and is passed through the first arm 2 and the second arm 3 via the first passage hole 24a, the second passage hole 24b, the third passage hole 34a, and the fourth passage hole 34b as described above. A charging connector 43 is mounted to the tip of the charging cable 40 pulled out of the distal end of the second arm 3. The charging connector 43 is connected to the charging port of the electric vehicle M, whereby the electric vehicle M is charged. The charging port is provided on the left side shown in
The charging cable support arm 10 is mounted to a wall face B at a height of, for example, 180 centimeters which is higher than the height of the electric vehicle M. The length of each of the first arm 2 and the second arm 3 is, for example, 90 centimeters (about 180 centimeters when both of the first arm 2 and the second arm 3 are combined together). By employing these dimensions, even when the charging port is arranged on the side opposite to the wall face B of the electric vehicle M, charging can be performed without the charging cable 40 being drawn around.
As described above, the support member 1 is fixed to a position higher than the electric vehicle M, and charging is performed by use of the charging cable 40 supported by the arms 2 and 3 which are foldable in two stages. Thus, even in a parking area without a ceiling, the charging cable 40 can be moved in a preferable manner.
The distal end of the second arm 3 can be moved, about the installation portion of the wall face B serving as the center, along the arc of a substantially semicircular shape having a radius of a length obtained by adding the length of the first arm 2 and the length of the second arm 3 together. Moreover, the distal end of the second arm 3 can be moved, about the distal end of the first arm 2 serving as the center, along the arc of a substantially semicircular shape having a radius of the length of the second arm. Thus, the fourth passage hole 34b that is a charging cable pull-out hole provided at the distal end of the second arm 3 can be moved in a wide range. Accordingly, the area where the charging cable 40 is suspended is wide, and for any position of the charging port of the electric vehicle M, charging can be performed without bringing the charging cable 40 into contact with the ground. Thus, dragging the charging cable 40 to cause deterioration thereof, making the charging cable 40 dirty with mud, or the like is eliminated.
Moreover, the second arm 3 folded to face the first arm 2 is maintained by the second magnet 22. Since the state where the first arm 2 is parallel to the wall face is maintained by the first magnet 14, while the charging cable support arm 10 is not used, the charging cable support arm 10 can be held in close contact with the wall face B.
In the charging cable support arm of the above embodiment, the first arm 2 and the second arm 3 are each formed by bending a steel plate, but existing metal square pipes may be used. Further, in the above embodiment, the charging cable support aim is mounted to a wall face, but a support post may be arranged adjacent to a parking area and the first arm 2 may be rotatably mounted to the support post.
Still further, in the above embodiment, in the course of passing the charging cable 40 from the first arm 2 to the second arm 3, the charging cable 40 is once downwardly exposed to the outside to be slack before being inserted into the second arm 3. However, the charging cable 40 may be directly passed from the first arm 2 to the second arm 3 without being exposed to the outside.
The present invention has been described with respect to charging of the electric vehicle M. However, it is understood that the present invention is preferably used in a plug-in hybrid vehicle provided with a charging function.
